Tested-by: Vinicius Pedrosa <vinicius.eduardo.pedrosa@gmail.com> # Radxa Cubie A7Z
Tested with the posted prerequisites and my local board DT. POW_MOD_SEL
reads back 0x05555555 on the main PIO and 0x00055555 on R-PIO, and
UART0, MMC0 at 3.3 V, R-I2C0/PMIC and GPIO interrupts on eight main PIO
banks worked.
